The best supported full-paper mock here is Vision Test 13201. Vision 13199 is usable but uneven, and Vision 13200 is the weakest. The older Mihir-generated runs are valuable for CA-plus-concept practice and often handle current-affairs linkage better than the weaker Vision papers, but they should not be treated as a one-to-one replacement for a full timed mock.
Source base: official GS1 PYQ PDFs from 2017-2025, three Vision IAS mock PDFs from mock/, and three older production runs exported from Mihir's hosted quiz set on March 23, 2026.

Noticeably below PYQ quality. Fails fundamentally in Current Affairs by testing magazine trivia and relies on outdated elimination tricks using extreme words.
Official baseline
What 2017-2025 PYQs reward now
From 2017 to 2025, the UPSC GS1 Prelims paper evolved from relying on traditional knowledge and standard elimination techniques to testing deep conceptual clarity and structural understanding. The introduction of 'How many pairs/statements' formats neutralized rote elimination, forcing candidates to know exact details. Current affairs shifted from isolated trivia to applied concepts, blending static syllabus with contemporary developments.
2017-2019
Era of Standard Elimination. Questions featured multiple statements where identifying one definitively wrong statement often revealed the correct answer code.
2020-2021
Rise of Unconventional Themes. Increased focus on agriculture, sports, and niche technologies. Distractors became more plausible, requiring deeper static knowledge.
2022-2023
The Elimination Killer. Introduction and dominance of 'Only one pair', 'Only two pairs', and 'Statement I & II' (Assertion-Reasoning) formats, demanding absolute certainty over partial knowledge.
2024-2025
Conceptual Consolidation. A balanced mix of assertion-reasoning and pair-matching, with a heavy emphasis on applied static knowledge, environmental concepts, and macro-economic fundamentals rather than rote facts.
Hallmark traits
Subtle phrasing traps that test reading comprehension as much as factual knowledge.
Integration of multiple disciplines within a single question (e.g., Geography and Economy).
Emphasis on core concepts over fringe trivia.
Use of absolute certainty formats ('How many pairs') to neutralize guesswork.
Focus on the practical application of technologies rather than just their definitions.
CA integration rule
UPSC integrates current affairs by using contemporary events as a springboard to test foundational static concepts. Instead of asking 'what' happened, the questions explore the 'why', the 'how', and the constitutional, economic, or geographical principles underlying the event. This prevents the exam from becoming a test of magazine trivia and ensures it evaluates a candidate's holistic understanding of the subject matter.
Dimension
What good looks like
Low-quality failure mode
Distractor Quality
Distractors are highly plausible, drawn from related concepts or common misconceptions, forcing the candidate to differentiate based on precise conceptual boundaries.
Using obvious extremes (e.g., 'all', 'never') or completely unrelated facts that make the wrong options easily identifiable without deep knowledge.
Question Formatting
Utilizes 'How many statements/pairs are correct' and Assertion-Reasoning formats appropriately to test comprehensive knowledge rather than just tricking the student.
Overusing traditional 1, 2, 3 codes where finding one error solves the whole question, or forcing the 'Only one pair' format on trivial data.
Static-Current Linkage
Current events are used as a hook to test the underlying static concept (e.g., a news item about a constitutional crisis leading to a question on the Governor's discretionary powers).
Asking direct, magazine-style trivia (e.g., 'Who won this award?' or 'Where was this summit held?') without any conceptual depth.
Subject Depth (Economy & Environment)
Tests application of concepts (e.g., how inflation impacts bond yields, or the ecological role of a specific species) rather than just definitions.
Relying on rote memorization of indices, reports, or basic definitions without testing the 'why' or 'how'.

Vision IAS Test 13199
reasonably close
7/10
The paper does a commendable job of adopting the recent UPSC structural shifts, particularly the heavy reliance on the 'How many statements/pairs' format. It tests conceptual clarity well in Economy and Polity, though it occasionally falls back on coaching-style factual traps and basic trivia in Geography and Current Affairs.

Strongest aspects
Extensive and appropriate use of the 'How many statements/pairs' format, effectively neutralizing rote elimination techniques.
Strong conceptual questions in Economy, focusing on macroeconomic fundamentals like inflation, unemployment types, and the Phillips Curve.
Polity questions that test structural and applied understanding (e.g., the utility of DPSPs, federal features) rather than just memorization of Articles.
Main weaknesses
Some Geography questions are overly basic and resemble older, pre-2017 UPSC patterns (e.g., identifying the atmospheric layer for radio signals or states on the Tropic of Cancer).
Current Affairs questions occasionally rely on magazine-style trivia, such as exact member counts of committees or specific historical awards, rather than applied concepts.
Use of predictable factual traps, such as swapping ministries or altering specific percentages, which lacks the subtle phrasing of real UPSC distractors.
How to use it
Highly useful for candidates looking to build stamina and confidence with the 'How many statements/pairs' format. It serves as a strong diagnostic tool for conceptual clarity in Economy and Polity, though candidates should not over-index on the factual trivia presented in the Current Affairs sections.
Vision IAS Test 13200
noticeably below PYQ quality
4/10
The paper attempts to mimic recent UPSC trends by incorporating the 'How many statements/pairs' format, but it fundamentally fails in its treatment of Current Affairs and relies too heavily on rote memorization. The CA questions are pure magazine trivia rather than applied static concepts. Additionally, traditional elimination techniques still work too well on many questions due to the use of obvious extreme words.

Strongest aspects
Inclusion of the 'How many statements/pairs' format in several questions (e.g., Q3, Q4, Q6, Q13, Q34, Q50) to neutralize guesswork.
A few strong conceptual questions in Economy and Environment (e.g., Q9 on GDP externalities, Q72 on RBI sterilization, Q81 on Allen's Rule).
Good use of paragraph-based personality identification questions (Q60, Q99) which aligns with traditional UPSC history questions.
Main weaknesses
Current Affairs questions are almost entirely magazine-style trivia (e.g., Q26, Q32, Q49, Q66, Q92) without any linkage to foundational static concepts.
Over-reliance on traditional 1, 2, 3 elimination formats where extreme words ('completely', 'all') easily give away the answer (e.g., Q14, Q79).
Severe lack of Assertion-Reasoning (Statement-I and Statement-II) questions, which are highly prominent in 2024/2025 UPSC papers (only Q9 uses this format).
Many history and art & culture questions test obscure rote facts rather than broader structural or cultural understanding.
How to use it
Useful for basic static syllabus revision and getting accustomed to the 'How many' format. However, candidates should strictly ignore the trivia-heavy Current Affairs questions, as memorizing such isolated facts is counterproductive for the modern UPSC Prelims.
Vision IAS Test 13201
reasonably close

Strongest aspects
Excellent adoption of the 'How many statements/pairs' format to neutralize guesswork.
Good conceptual depth in static subjects like Economy (e.g., GDP vs GNP, PDI) and Polity.
Appropriate use of Assertion-Reasoning questions for geographical and political concepts.
Main weaknesses
Over-reliance on 'Term X seen in news' format for Current Affairs, lacking the applied depth of real PYQs.
Some factual questions are too data-heavy or rely on exact rankings and percentages, which UPSC generally avoids.
How to use it
Highly useful for building stamina and accuracy for the 'How many statements' format. Good for revising core static concepts in Economy and Polity. However, candidates should supplement the CA portion with deeper, application-based reading rather than just memorizing terms.

Vision IAS Test 13200
Q26, Q49, Q66, Q92
Violates the recent UPSC trend of applied science and current affairs. UPSC asks about the application or underlying principles of technologies, not just 'which country launched it' or 'what is the name of the rocket'.
Vision IAS Test 13200
Q14, Q79
Uses extreme words ('completely absent', 'All industries') which makes traditional elimination too easy. Modern UPSC distractors are highly plausible and avoid such obvious traps.
Vision IAS Test 13201
Q4, Q6, Q8, Q30, Q43, Q46, Q48
Perfectly mirrors the 2023-2024 'Elimination Killer' era by forcing absolute certainty through 'How many statements' formats.
Vision IAS Test 13201
Q5, Q7, Q25, Q47, Q53
Uses Statement-I/Statement-II (Assertion-Reasoning) formats effectively to test conceptual linkages, aligning with the 2024-2025 conceptual consolidation phase.
Vision IAS Test 13201
Q80, Q81, Q92, Q94, Q95, Q97, Q99
Deviates from recent PYQs by asking direct, magazine-style trivia ('What is this term?') instead of testing the underlying mechanism or application of the technology/initiative.

Generation verdict
Strong and useful for CA-plus-concept practice, especially in the older runs sampled here, but not a full-mock replacement. Many questions capture recent UPSC structural tendencies well, while others remain closer to direct recall or ordinary generated-quiz material.
Why the CA worked better
The CA handling is generally better than the weaker Vision papers because many items use news as an entry point into static concepts rather than staying at magazine-trivia level. But it is not uniformly 'static-first': some items are still closer to direct factual recall than deep applied CA.
Oracle revalidation
A delegated oracle-style revalidation found that the Vision ordering is broadly correct but the earlier Gemini analysis overstated the Mihir generated runs by treating them as full mocks and by using language like 'flawless' and 'perfectly mirrors'.
Preparation impact
How to align prep from this audit
What to stop doing
Do not let trivia-heavy mock CA sections reset your sense of difficulty. The modern paper punishes shallow elimination and rewards mechanism-level understanding.
What to do more
Stop memorizing magazine-style current affairs trivia like award winners or summit locations; focus entirely on the underlying static concepts of news events.
Build absolute certainty in your knowledge. The 'How many pairs' format has killed traditional elimination tricks, so partial knowledge is now a liability.
Prioritize understanding mechanisms in Economy and Environment (e.g., how inflation impacts bond yields) over rote definitions and indices.
Use Vision 13201 as the best of these full-paper mocks, and use the older Mihir-generated runs as a separate CA-plus-concept bank rather than as your only mock benchmark.
